Title: Purification of fatty acid amide
Inventor: NORUBERUTO DERUPINKUHAUSU
IPC: C07C231/24
Filed: 1993-08-12
Abstract: PURPOSE: To obtain highly pure fatty acid amide containing little nitriles by neutralizing a crude fatty acid amide with an aqueous alkaline solution and then distilling the neutralized mixture. By this process, the crude fatty acid amide can be purified even when the crude fatty acid amide contains impurities in a high concentration.  
     CONSTITUTION: The purified fatty acid amide is obtained by first adding an aqueous alkaline solution (e.g. NaOH) to a crude or unpurified fatty acid amide (preferably, a mixture of oleamides) in order to neutralize fatty acids contained in the fatty acid amide, and then distilling, preferably, by using a film evaporator. The neutralization is preferably carried out by adding 5-60 wt.% of aqueous alkaline solution to the crude fatty acid amide, in the weight ratio of the crude fatty acid amide to the alkaline solution of 10:1 at 80-100°C under stirring. The distillation is preferably carried out with a single-stage distillation process when the crude fatty acid amide has an acid content of 3-4 wt.% and the quantity of excess NaOH is not more than 1-1.2 mole, on the other hand, the distillation is preferably carried out with a two-stage distillation process when the acid content or the quantity of excess NaOH is higher than each value mentioned above.

Title: Callback signal receiving method
Inventor: HAISHI KATSUYUKI
IPC: H04W76/02
Filed: 1991-08-12
Abstract: PURPOSE:To realize the callback signal receiving method in which the movement of a radio terminal equipment is taken into account by, informing the arrival of an incoming call to not only a base station having made communication but also to other base stations in the case of the reception of a callback signal. CONSTITUTION:In the radio communication system provided with plural base stations and a line controller, a caller base station being an object of callback and other base stations in a same calling area being objects of callback are registered in a fixed data section on the occurrence of the callback. When a callback with respect to a call whose channel is reserved takes place after the end of the call, the fixed data section is referenced to inform the arrival of the callback to not only the base station #j having taken part in the reserved call but also other base stations (e.g. plural base stations #a, #k adjacent to the station #j in the same calling area). Thus, even when the radio terminal equipment is moved from the area of the base station #j to the coverage of the base station #a, the callback is able to reach the terminal equipment.

Title: Disc brake
Inventor: ARIMITSU SATOSHI
IPC: F16D65/095
Filed: 1984-09-27
Abstract: PURPOSE:To reduce the weight of a discbrake by installing a sleeve between a shaft member and a pad and setting the axis center of the sleeve and the axis center of a shaft member into eccentric state and reducing the bending of the pin member, thus reducing the thickness of the pin member. CONSTITUTION:The axis center P of a sleeve 19 is set eccentric from the axis center Q of a pin member 17. In other words, the small-diameter hole part 19a of the sleeve 19 is formed eccentric for the axis center P of the sleeve 19, and the pin member 17 is inserted in slidable ways. Therefore, the gap between the pin member 17 and the inner wall surface of the sleeve 19 can be made concentrically uniform by the revolution of the sleeve 19, and the both pin members 17 and 17 receive brake reaction force in equal degree, and the bending can be reduced further. Therefore, the necessity of increasing the thickness of the pin member 17 is obviated, and the reduction of weight is permitted.

Title: Battery capable of judging thermal history
Inventor: AKATSUKA TAKATOSHI
IPC: H01M50/583
Filed: 1986-08-28
Abstract: PURPOSE:To easily judging serious damage such as short-circuit by arranging a sensor which irreversely changes by heat on the surface of a protecting element which is visible from the outside of a battery. CONSTITUTION:When a circuit is short-circuited by a malfunction, excess current flows through the circuit, and a PTC element 1 is heated by Joule heat and its temperature is increased. The resistance of the PTC element is sharply increased by the heat, and the color of a sensor 5 on the surface of the PTC element is changed. Increase in the resistance of the PTC element stops the excess current in the circuit to protect it. Since the color change of the sensor is irreversible, even if the PTC element 1 is recovered, the color change of the sensor is not recovered.

Title: Spraying method of spacer member to liquid crystal substrate
Inventor: KUBOTA NOBUO
IPC: G02F1/1339
Filed: 1984-09-27
Abstract: PURPOSE:To spray uniformly a spacer member to a liquid crystal substrate in a wider range by jetting a dispersion medium from a nozzle into the vessel in which the substrate is not housed and housing the liquid crystal substrate into the vessel after the jetting of the dispersion medium from the nozzle. CONSTITUTION:A shutter 10 is opened and the spacer member 2 incorporated into the dispersion medium is jetted from the nozzle 5 while the liquid crystal substrate 1 is not housed onto a drawer 6 having the base constituted of a wire net. The shutter 10 is thereafter closed and the drawer 6 is drawn out when there is no more gaseous flow in the vessel body 4 and the member 2 falls by gravity, for example, upon lapse of 5min after the jetting. The substrate 1 is imposed on the drawer and the drawer is again gently housed into the body 4. Then the spacer member 2 is allowed to fall by gravity on the substrate 1 for, for example, 2min. The spacer member 2 is thus sprayed in the uniform state onto the substrate without being affected by the disturbance of the gaseous flow in the vessel during the jetting of the dispersion medium.
